Question

Along with some other reasons, the formation of galaxies is complicated because gravitational interaction between stars, thermodynamics of the gases involved as well as the energy produced by the stars. However, regardless of the physics of their formation, galaxies are accepted as generally containing all of the following except:

Answer 1

Galaxies are accepted as generally containing all of the following:

Stars: Galaxies contain stars of various ages, sizes, and types. These stars are held together by gravitational force.

Gas and dust: Galaxies contain gas and dust, the raw materials for forming new stars. Gas and dust are also crucial for regulating the temperature and chemical composition of the galaxy.

Dark matter: Galaxies are believed to contain significant amounts of dark matter, which does not interact with light but exerts a gravitational force on visible matter.

Supermassive black holes: Most galaxies are believed to contain a supermassive black hole at their center, which plays a key role in regulating the growth and evolution of the galaxy.

One thing that galaxies are generally not accepted as containing is life beyond our own planet. While the possibility of extraterrestrial life is an intriguing subject of speculation and scientific investigation, no confirmed evidence of life beyond Earth has been discovered in any galaxy.
